HYDRO-TRIP PRESSURE SUB
The hydro-trip pressure sub provides a means to set
Hydraulically actuated tools by applying the
tubing pressure required for activation.
Setting is achieved by circulating a ball to a
seat in the sub and applying sufficient pressure
to activate the setting mechanism in the tool.
Further pressure is applied to the ball, shearing
brass screws and sending the ball down the tubing.
Following setting, the sub provides an open bore
for passage of drop balls or wireline equipment.
